Timing chain replacement

[Ejbierman]

I have a 1990 GMC Sierra 1500 4.3 v6 2wd. My timing chain slipped causing my gears to be out of alignment. I tore it down timing chain was worn out. Before i go to put it back together i need to know how I put it back into time.

Cyl number 1 at top dead center of compression stroke and align the cam gear to meet the mark on the crank gear. Add chain and put it back together

[Ejbierman]

Is it possible to get it to tdc if the gears and chain are off?

of course you can.

 

there is something to think about.

timing chains don't just wear out...you got a serious problem elsewhere.

 

odd fire v6 to boot.

 

I wore down one on an old 350, it was the block bent. Dumpster bound.

I got the crankshaft and cam shaft in time got it all back together. Still no start replaced the distributor. Put it back at TDC and the rotor is pointing between 1 and 6 on the cap.

Did you do timing chain on your 96? My 97 runs great at 205k and all original. Except intake manifold gasket of course. Should I be worried about chain slipping or jumping?
